Commentary on “Effects of patients' understanding and choice of surgical types on postoperative outcomes of Peyronie's disease: a single-center retro…
2021
Surgical correction can be considered for treating patients with a chronic phase of Peyronie's disease (PD) and persistent penile curvature. In clinical practice, some patients pay too much attention to surgical complications and refuse the recommended feasible surgical types. Meanwhile, they require operations according to their preferences. This study aimed to evaluate the effects of patients’ own choice of surgical type on postoperative satisfaction. This retrospective study analyzed data from 108 patients with PD who underwent surgical correction according to doctors’ recommendations or patients’ own demands. The objective and subjective surgical outcomes were assessed. Patients’ unders…
Effects of 12-month home-based physiotherapy on duration of living at home and functional capacity among older persons with signs of frailty or with …
2018
Health concerns, such as frailty and osteoporotic fractures decrease functional capacity and increase use of health and social care services in the aging population. The ability to continue living at home is dependent on functional capacity, which can be enhanced by rehabilitation. We study the effects of a 12-month home-based physiotherapy program with 12-month follow-up on duration of living at home, functional capacity, and the use of social and health care services among older persons with signs of frailty, or with a recently operated hip fracture. This is a non-blinded, parallel group, randomized controlled trial performed in South Karelia Social and Health Care District, Finland (popu…
The effect of choice complexity on perception of time spent choosing: When choice takes longer but feels shorter
2009
Two studies examine the effect of the complexity of the choice environment on the perceived duration of the time spent choosing. The experiments demonstrate that the estimation of the time spent making a decision is affected by the number of options available in the choice set. In Experiment 1, participants having to choose 1 of 24 mobile phones tended to underestimate the time spent whereas participants confronted with the choice of 6 mobile phones tended to overestimate the actual time spent. Experiment 2 corroborates this finding, in the presence of varying degrees of attribute correlation. We conclude with theoretical and practical implications for marketers. © 2009 Wiley Periodicals, I…
Brand love in progress – the interdependence of brand love antecedents in consideration of relationship duration
2015
Purpose – This paper aims to investigate the dynamic nature of consumer–brand relationships and, in particular, the passionate dimension of brand love. It explores the relevance of the two dimensions of the identification construct (inner and social self) for the creation of passionate love for a brand. More precisely, it attends to the possible mediating character of identification between the perceived utilitarian or hedonic value and passionate brand love. These effects are analysed in consideration of the moderating effect of relationship duration taking a further-reaching perspective and contributing to the understanding of the transformation of the brand love construct within a long-…
Broadband tuning of a long-cavity all-fiber mode locked Thulium-doped fiber laser using an acousto-optic bandpass filter
2019
A long-cavity passively mode-locked thulium-doped all-fiber laser is reported incorporating a tapered acousto-optic tunable bandpass filter (AOTBF). The operation of the AOTBF relies on the intermodal coupling between core and cladding modes when a flexural acoustic wave propagates along an 80-microm tapered fiber. The filter works in transmission and exhibits a 3-dB bandwidth of 9.02 nm with an insertion loss of 3.4 dB. The laser supports ultrashort pulse generation at a low repetition rate of 784.93 kHz. Optical pulses with 2.43 nm of optical bandwidth and 2.1 ps pulse duration were obtained in a broad tuning range from 1824.77 to 1905.16 nm.
From Above Threshold Ionization to Statistical Electron Emission: The Laser Pulse-Duration Dependence ofC60Photoelectron Spectra
2000
The photoelectron spectra of C60 ionized using a 790 nm laser with pulse durations varying from 25 fs to 5 ps have been determined. For 25 fs pulses, in the absence of fragmentation, the ionization mechanism is direct multiphoton ionization with clear observation of above threshold ionization. As the pulse duration is increased, this becomes dominated by a statistical ionization due to equilibration among the electronic degrees of freedom. For pulse durations on the order of a ps coupling to the vibrational degrees of freedom occurs and the well-known phenomenon of delayed (ms) ionization is observed.
Growth of titanium oxynitride layers by short pulsed Nd:YAG laser treatment of Ti plates: Influence of the cumulated laser fluence.
2009
International audience; Titanium oxynitride layerswere formed by surface laser treatment of Ti plates in air using a Nd:YAG laser source of short pulse duration about 5 ns. The cumulated laser fluence was varied in the 100–1200 J cm2 range and its influence on the composition and the structure of the formed layers was studied by different characterization techniques providing physico-chemical and structural information. It was shown that the laser treatment induces the insertion of light elements as O, N and C in the formed layer with the amount increasing with the laser fluence. The in-depth composition of the layers and the co-existence of different phases were also studied. The way in wh…
The effects of linearly increasing flip angles on 3D inflow MR angiography
1994
As recently demonstrated, spin saturation effects in 3D time-of-flight (TOF) MR angiography (MRA) can be reduced by using RF pulses with linearly increasing flip angles (ramp pulses) in the main direction of flow. We developed a model for calculating the signal distribution of proton flow within the excitation volume (slab) for different ramp slopes and compared the results with the measured distribution for the lower-leg arteries. The ramp pulses were generated using the Fourier transformation of the desired excitation profiles. With a bandwidth of 6 kHz and a pulse length of 2.56 ms satisfactory ramps with variable slopes were generated and applied in a standard flow-compensated 3D FISP s…
